The present invention relates to a wobble preventing nut and, more specifically, relates to a wobble preventing nut comprising: a first nut which has a first coupling hole formed to be coupled with a bolt; a second nut which has a second coupling hole, coupled with the bolt with the first nut; a combining hole formed to be dented along a surrounding of the coupling hole of any one between the first nut and the second nut; a combining protrusion formed to protrude from an other one between the first nut and the second nut in order to be inserted into the combining hole; and a wobble preventing unit which has elasticity, is positioned between the combining protrusion and the combining hole, and prevents wobbling by improving a mutual binding force between the first nut and the second nut which are coupled with the bolt as a gap is prevented by filling the space therebetween when being inserted into the combining hole. The present invention like the above is able to improve product reliability by preventing wobbling and looseness caused by an external impact or repetitive vibrations by solidly coupling the first nut with the second nut without a mutual wobble by the wobble preventing unit when being coupled with a bolt. |
